HI-1570
HEAT SINK - ESOIC PACKAGE
The HI-1570PSI/T/M all use a 20-pin thermally enhanced
SOIC package. The package include a metal heat sink
located on the bottom surface of the device. The heat
sink should be soldered down to the printed circuit board
for optimum thermal dissipation. The heat sink is also
electrically isolated and may be soldered to any
convenient power or ground plane.
THERMAL CHARACTERISTICS
APPLICATIONS NOTE
Holt Applications Note AN-500 provides circuit design
notes regarding the use of Holt's family of MIL-STD-1553
transceivers. Layout considerations, as well as
recommended interface and protection components are
included.
